[Feature Request] Move query categorization to query insights plugin

[deshsidd]

Is your feature request related to a problem? Please describe

Query categorization changes to increment counters for search query related metrics currently resides on the search path and occurs before the request.

Describe the solution you'd like

Move these changes to the query insights plugin and make sure the incrementing of counters happens separately from the search path.

Describe alternatives you've considered

Another option is to keep query categorization changes as is. However, this will lead to additional overhead on the search path. Furthermore, we need to tie query latency, cpu, memory with the query categorization data which will only be possible if we increment the counters after the request is completed and the query latency and resource usage data resides inside the plugin.

To support the above and to prevent doing these counter increments on the search path, we need to move query categorization changes to the query insights plugin.
